TCC-I System-Level Indicators

System-Level LEDs

Definition

Red CRIT LED

Used to indicate critical alarms in the network at the local terminal.

Red MAJ LED

Used to indicate major alarms in the network at the local terminal.

Yellow MIN LED

Used to indicate a minor alarm in the network at the local terminal.

Red REM LED

Provides first-level alarm isolation. The REM LED turns red when an alarm
is present in one or several of the remote terminals.

Green SYNC LED

Used to indicate that node timing is synchronized to an external reference.

Green ACO LED

After pressing the alarm cutoff (ACO) button, the green ACO LED
illuminates. The ACO button opens the audible closure on the backplane.
ACO state is stopped if a new alarm occurs. After the originating alarm is
extinguished, the ACO LED and audible alarm control are reset.
